Sloths only defecate once a week and it is the only reason they leave the trees for the ground.

If your sausage and bacon breakfast is taking a little longer than usual to move its way down your tummy, spare a thought for the poor sloth – it takes him 30 days to digest just one leaf.

All sloths actually have three toes, but the two-toed sloth has only two fingers.

Sloths may not look very menacing or even dangerous, but if their ancestors caught you, they could make you wish for a quick and swift death. As early as 10,000 years ago in the Pliocene epoch, the giant Megatherium (aka “the giant sloth”) roamed the Earth. They lived in what is now South America and have been described as the same size as the modern rhinoceros before their extinction. They were mainly herbivores, but some paleontologists suggest they could have been “opportunistic carnivores” if they needed to defend themselves from predators or other Megatheriums.
